The first thing you need to do is read the "sticky" at the top of this forum regarding equipment, etc.
The second thing is to purchase a reloading manual authored by Speer, Lyman, Sierra, Hornady, etc. A used one on Ebay is just fine, as long as it was published within the last 20 years or so.
After you have done the first two above, then you can start reloading. Trying it before that is asking for serious trouble.
Reloading is not "rocket science" but unless you understand the very basic fundamentals, you can get in real trouble and injure yourself and others near you with the "wrong handload."
The sticky & books will give you very good advice and will allow you to start from the very beginning. Problem with many of us that have been reloading for many, many, years is that we take for granted those things that a newcomer to reloading may not know. The reloading manuals will cover those very basic things that we may forget or skip over.
